Walk into Fabul Castle where the guards at the door will greet Yang and tell him the king wishes to see him. Walk forward up several staircases to the throne room where the King of Fabul will meet Yang and the party and request everyone's assistance to defend Fabul from an invasion by Baron. Agree to it (you'll actually get the choice), and then Edward, Yang and Cecil will be sent to defend the castle entrance with Rosa and Rydia remaining behind.

You'll be thrust to the scene outside where you'll immediately be attacked by a Captain and two Baron Warriors. Quickly eliminate them (although the Red Wings will begin to bomb the castle, so you'll have to retreat back indoors). Once back inside, the party will be attacked by some monsters (this time a party of one Leshy, one Domovoi, and one Sahagin... an easy battle.) With this second wave of enemies slain, the party gets pushed even deeper into the castle.

The party will again be attacked by a party of two Baron Warriors and a Captain - eliminate them much like you did the first. In the next room a monster disguised as a Fabul monk will unlock the door of the throne room and then attack the party. Kill this lone Gargoyle easily, and then the next wave of monsters that comes at you as well. When the party attempts to escape the room and defend the Crystal Room directly, Edward falls and the party must rescue him from another two Baron Warriors/Captain combination. Kill the foes before retreating into the final chamber.

Here the party will need to defend the crystal, for there is no where else to run after this. Unfortunately, it is not meant to be - Kain, clearly under Golbez's spell, attacks Cecil (you can't do anything about it so don't even bother fighting him), and after showing some remorse, Golbez himself appears.

Golbez knocks the entire party out (save Rydia) and orders Kain to steal the crystal, which he does. Meanwhile, he also kidnaps Rosa to "raise the stakes." When he leaves, Rydia revives the party (although you've now lost your party's primary healer, so things get a little more difficult from here on out on long expeditions). After the party discusses things further, you gain control of the four-man party once more.

We now need to find the goods that are here to find in the castle, and also we must talk to the people around the castle to see what's going on, and buy some goods as well. In the throne room, search the jar in the upper lefthand corner to find Hermes' Shoes. If you go to the upper right corner of the room, you can press a button on the floor to reveal a hidden door and hidden passageway to a small room with three more treasure chests. Within them, retrieve some Spider's Silk, an Ether, and a Demon Shield (which you should equip on Cecil.) Talk to the King's chancellor in the throne room as well to find that he sustained injuries in the siege.

If you go down to the next room, circle around to the bottom of the room and take it to the outside of the castle (but atop of the castle, if you will). Flanking your position will be two doors, each leading to their own tower. In the righthand tower on the second floor, you can find a Bacchus's Cider in one of the jars to the right of the bar, as well as a Tent in the third floor, which is the King's bedroom (so make sure to talk to him.) In the other tower, you can go to the third floor to talk to Yang's wife and to the second floor to talk to some bed-ridden soldiers, but the treasures are all on the first floor here. Out of the jars and treasure chests, grab:Rage of Zeus, Potion, Antarctic Wind, and a Bomb Fragment.

From here you should really just run around the rest of the castle to talk to anyone you haven't talked to yet. Also, swing by the Weapons shop to buy all new armaments for Cecil and some claws for Yang. Entering the Inn to the left of this shop will allow you to stay there for free while a ship is sent to the eastern harbor next to Fabul for your use. Additionally, an item shop is right there if you need any goods (you should have 99 Potions by this point, at least... and a lot of Phoenix Downs as well.)

Once you enter the boat on the eastern shore outside of Fabul, Yang's wife will see the group off. However, on the ship, things don't go exactly as planned. While sailing along, Leviathan comes out of the water and causes a humongous whirlpool that the party cannot seem to escape. Meanwhile, Rydia and Yang are thrown off of the boat and Edward is knocked out.

After the huge wreck, Cecil wakes up on a beach all by himself and has no clue where is. Additionally, he's all alone. But as he regains consciousness and walks eastward along the peninsula he's on, he approaches a town, and will not be alone for long...
